As part of the SUMO project, the company Eles is developing a system that predicts the variable maximum permissible current load of power lines and transformers, using weather model data and measured atmospheric variables, as well as current and predicted loads of network elements. This thesis describes the development of a tool that analyzes SUMO results for N-1 topology. The tool enables a quick analysis of SUMO system results in the Microsoft Excel pivot tables and the data is being imported through queries from a PostgreSQL database.
To understand how the tool functions we first need to know both the many parts that make up the tool as well as the background for the SUMO project. Therefore, in this thesis, I first present the loads of power lines, the SUMO project, and the individual tools I used to develop this tool.
The following is a description of development of the latest version of the tool. The description of the development is divided into phases describing the construction of individual tool elements and explaining the role of the element in the tool.
The last section shows how to use the tool (namely data display and data filtering) and also the testing of the tool, where progress in speed and reliability is shown compared to the first version of the tool.
